flights to tenerife

We are looking to go to tenerife for a week in October or November.Package deals are still expensive(2 adults and 2 children).We have found a fantastic villa with private pool for €350 on owners direct web site and so just need to find flights do you know of any other airline apart from aerlingus and Ryan air?
many thanks

Thomas Cook go out of Belfast on Tuesdays and Fridays, so far as I know you can book flight only.
